WET GAS-METER.

Specification of Letters Patent.

Patented July 10, 1906.

Application filed September l l 1905. Serial No. 278.059.

To all whom it nuty concern.-

Be it known that I, JOHN OSWELL JONES, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in WVet Gas-Meters, of which the following is a specification.

This invention relates to gas-station me ters of that class commonly known as Wet meters, and has for its object to improve the construction of the same to the end that the capacity of the meter is very materially augmented.

The invention consists of a cylindrical drum secured to a shaft passing longitudinally therethrough, said shaft being journal'ed in suitable brackets secured to the end walls of a surrounding casing.

Similar letters refer to the same parts in all of the figures.

In the drawings forming part of this specification, Figure 1 is a longitudinal section through the casing and drum. Fig. 2 is a section through Fig. 1 on the line 1 1. .Fig. 3 is a similar section on the line 2 2, the end of the drum-shaft being shown in elevation and its supporting-bracket being omitted. Fig. 4 is an enlarged detail of the gas-inlet pipe and packing.

In the drawings, a is a cylindrical casing made either of cast-iron or steel, solid. or sectional, fastened together with suitable fastenings, such as bolts or rivets, with packing to make a gas-tight joint. The said casing is divided longitudinally to form a lower sec tion a and an upper section or cover a, whose lower edges r are adapted to fit into a gutter 1-, formed on the upper edges of the lower section, thus forming an air or gas tight closure. The cover is held to the lower section by any suitable fastening, as t in Figs. 2 and 3.

Secured to the inner faces of the end walls of the lower section a are brackets 0 and p, on which is supported a shaft q, carrying and to which is secured a drum 1). WVithin the drum 1) are arranged a plurality of helical vanes d, secured to the end walls of said drum and having strengthening-ribs e. The vanes (Z are secured to the end walls of the drum 6 at such an angle that pockets 8 are formed which receive the impulse of the inflow of gas. At one end of the drum 1) is formed a domeshaped chamber 1) or dry well. The section a and the drum 1) are filled with water up to the bottom of the uppermost vane d in Fig. 1. This provides an effective seal. A pipe 7c is removably secured to the casing a by any suitable means, as the screw-threaded sleeve m, screwed into the casing, and a nut Z, between which and the sleeve m is packin n. A pipe j, which is also held by the nut? and sleeve m, projects within the dry-well chamber 6 and turns upward above the wa ter. Fast upon the end of shaft 9 is a gearwheel 9, which indicates conventionally one element of an indicating mechanism. An outlet-pipe it leads from the upper portion of the casing and serves to conduct the gas from the meter.

Gas enters through the pipes and k, filling the chamber b, and enters the passages (the sides of which are indicated on Fig. 3 by the letters x as) between the helical vanes, which are open at one end to the chamber b and at the other end to the interior of casing a. (See Fig. 3.) The Water seal, provided by filling the casing with water up to the point indicated by the horizontal line x in Fig. 1, prevents the gas from taking any path except that formed by the passages between the helical vanes. As the gas impin es upon the helical vanes the drumsis caused to revolve and actuate the indicating mechanism, as Will be readily understood. It will thus be seen that simple and efficient means are herein provided for effectively registering the flow of gas through the meter.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A gas-meter comprising a casing made in two sections and hinged together, the lower of said sections having ,a gutter formed around the edge thereof adapted to receive the edge of the upper of said sections, a drum rotatively mounted in said casing, vanes carried by said drum, ahead carried by the drum and forming a dry-well chamber, and an inlet-pipe leading from the exterior of the easing and having its inner end upturned and projecting through and above the inlet of the dry-well chamber.

2. A gas-meter comprising a casing made in two sections and hinged together, a drum rotatively mounted in said casing and having helical vanes, a head carried by the drum and forming a dry-Well chamber between the drum and said head, said head having an opening formed therethrough, a curved pipe the inner end of which-passes through the opening of the head and is upturned above the edge of said opening, said pipe having a extension into which a gas-inlet pipe is flange formed upon the opposite end thereof, threaded. 10 a sleeve threaded into the end of the casing, a In testimony whereof I affiX my signature packing-ring between said sleeve and said in presence of tWo Witnesses.
